Definitions

  • the invention relates to a three-pole cable connecting unit for a three-pole metal-encapsulated, compressed gas-insulated high-voltage switching installation, wherein the three cable connecting elements are introduced into a housing forming the encapsulation. Within the encapsulation are also disposed a three-pole isolating switch and possibly a three-pole ground. In addition one or two three-phase conductor branches are provided, the connecting planes of which, leading out of the housing wall, are perpendicular to each other, one conductor branch lying on an end wall of the housing.
  • a three-pole cable connecting unit is formed in such a way that the three cable connecting elements are introduced into the cylindrical housing on the end wall.
  • the elements are generally arranged in a plane parallel to the diametrical longitudinal plane of the housing and connect to fixed contacts of the three-pole isolating switch which are arranged generally in a plane lying at right angles thereto.
  • the movable contacts lie in this plane also, the isolating gaps in this plane being bridged by contact pins which extend at angles to each other.
  • Connecting conductors lead away from the isolating switch contacts in such a way that at the conductor branch leading out of the housing wall, the connecting conductors are positioned at the tips of an approximately equilateral triangle.
  • the cable connecting elements and a three-phase conductor branch are arranged on the end walls and another three-phase conductor branch is arranged perpendicular thereto on the cylindrical wall.
  • the connecting conductors are brought into the housing 1 from their equilateral triangle arrangement at the conductor branches to the generally parallel arrangement of the cable connecting elements, which permits the height of the housing to be small, since the three-pole isolating switch can be placed into a plane extending perpendicular to the diametrical longitudinal plane of the housing.
  • the driving mechanism for the contact pins and for the contacts of the optionally present ground mechanism can be of simple design and also located within the housing.
  • the isolating gaps are inclined toward one another within the plane of the isolating switch.
  • bent connecting conductors of the end wall conductor branch and the bent connecting conductors in the front wall conductor branch which originate either from the fixed or from the movable contacts of the isolating switch, are advantageously of identical construction, which greatly simplifies stockkeeping. Yet they form the tips of an approximately equilateral triangle in the conductor branch.
  • the contact pins per phase of the three-pole isolating switch and their actuating mechanisms on high-voltage potential as well as the fixed contacts of the isolating switch and those of the possibly present ground, are preferably fastened to the housing by insulators. It is especially expedient to use a shaft extending parallel to the diametrical longitudinal plane of the housing in the manner of a chord as a drive mechanism for the contact pins of the three-pole isolating switch.
  • the drive shaft of the optional ground is also preferably parallel thereto.
  • FIG. 1 is a longitudinal section view of a cable connecting unit designed according to the invention
  • FIG. 2 is a bottom plan view showing the lower end wall of the unit of FIG. 1;
  • FIG. 3 is a top plan view showing the upper end wall of the unit of FIG. 1;
  • FIG. 4 is a section view taken along the line IV--IV in FIG. 1;
  • FIG. 5 is a view partly in section of a modified form of the unit of FIG. 1, shown in a view similar to the upper half of FIG. 1;
  • FIG. 6 is a view corresponding to FIG. 3 of the modified unit of FIG. 5.
  • FIGS. 1-4 show an embodiment of a three-pole cable connecting unit housed within a metallic cylindrical housing 1 which forms an encapsulation for the unit.
  • the encapsulation is closed at its lower end wall 2 by a gas-tight cover 3, through which three cable connecting elements 4, 5 and 6 pass.
  • the cable connecting connecting elements 4, 5 and 6 are positioned side-by-side so that they lie generally in a plane extending parallel to the diametrical longitudinal plane 7 (shown by dashed lines in FIG. 2) of the housing 1.
  • the elements 4, 5 and 6 serve to guide cables respectively to the fixed contacts 9, 10 and 11 (see FIG. 3) of a three-pole isolating switch 12.
  • the contacts 9, 10 and 11 are arranged in a plane 8 (shown by dashed lines in FIG. 1) which is at right angles to the plane 7.
  • Each of the contacts 9, 10 and 11 is fastened to the housing 1 by means of an insulator 13.
  • the movable contacts 14, 15 and 16 of the three-pole isolating switch 12 also lie within the plane 8.
  • the isolating gaps 18 in plane 8 are bridgeable by the contact pins 17 (indicated in broken lines in FIG. 3) which extend at angles relative to one another.
  • two connecting conductors extend from each of the movable contacts 14, 15 and 16 of isolating switch 12 in fanned-out fashion to the three-phase conductor branches 19 and 20.
  • the conductor branch 19 is passed through the cylindrical wall of the housing 1 by means of the flange 21 (see FIGS. 1, 3 and 4).
  • the branch 19 comprises three connecting conductors 22, 23 and 24 which are fanned out from the movable contacts 14, 15 and 16 that lie generally parallel and side-by-side in plane 8, in such a way that at the conductor branch 19 the conductors 22, 23 and 24 are relatively positioned at the tips of an approximately equilateral triangle 45 (as shown by dashed lines in FIG. 4).
  • the other three connecting conductors 25, 26 and 27 also originating from the movable contacts 14, 15 and 16, respectively, lead to the three-phase conductor branch 20 which lies in the upper end wall 28 of the housing 1.
  • the conductors 25, 26 and 27 are fanned out so that at the conductor branch 20, they too lie at the tips of an approximately equilateral triangle 29 (shown by dashed lines in FIG. 3).
  • Each movable contact 14, 15 and 16 of the isolating switch 12 is fastened within the housing 1 by an insulator 30 mounted on a support 31.
  • the insulator 30 also supports the driving mechanism arranged within the housing 1 for the conact pins 17 of the isolating switch 12.
  • the pin driving mechanism comprises an angle lever 32, an insulating rod 43, a lever 44 and a drive shaft 33. These elements are articulated as shown in FIG. 1, so that when the drive shaft 33 is pivoted, the lever 32 drives the pin 17 linearly.
  • the drive shaft 33 extends parallel to the diametrical longitudinal plane 7 in the manner of a chord (as indicated by dashed lines in FIG. 3).
  • a drive shaft 34 for a grounding mechanism 35 is positioned parallel to the drive shaft 33 of the isolating switch 12.
  • the grounding mechanism comprises movable contacts 36 that serve to ground the fixed contacts 9, 10 and 11 of the isolating switch 12.
  • the grounding mechanism 35 is disposed on the support 37 which serves to fasten the insulators 13 of the fixed contacts 9, 10 and 11 of the isolating switch 12 inside the housing 1.
  • connection between the fixed contacts 9, 10 and 11 of the isolating switch 12 and the cable connecting elements 4, 5 and 6 is established by means of a coupling contact 38 which prevents the transmission of mechanical forces.
  • the three-phase conductor branch 20 brought out at the upper end wall 28 is formed by three connecting conductors 39, 40 and 41 which connect with the fixed contacts of the isolating switch 12.
  • Conductor 39 is connected with the fixed contact 9, conductor 40 with the fixed contact 10 and conductor 41 with the fixed contact 11.
  • the connecting conductors 39, 40 and 41 are fanned out so that they lie in the conductor branch 20 at the tips of an approximately equilateral triangle 42 (as shown by dashed lines in FIG. 6).
  • the bent connecting conductors 26, 27 leading to the movable contacts 14, 16 in FIG. 1 of the isolating switch 12 and the bent connecting conductors 39, 40 and 41 leading to the fixed contacts 9, 10 and 11 (FIG. 5), are all of the same construction.
  • the arrangement of these conductors in the conductor branch 20 takes the general form of an equilateral triangle 29, 42.
  • the connecting conductor 25, originating from the movable contact 15, is a straight pipe section.
